Orchid & nbsp Orchid Shizhai Orchid language VIII: seedling emergence rate and Orchid Seedling size

Combined with "discussion on ramet and seedling emergence rate of orchid seedlings", the ramet, seedling emergence rate and seedling size were discussed from the point of view of bluegrass itself and later management.

Seedling emergence rate and Orchid Seedling size

The emergence rate of bluegrass is related to the variety of orchid, the strong and thin of orchid, the size of orchid clump, cultivation and care, and the illuminance of the environment. I will start from the above several aspects, combined with my own practice and the knowledge learned from books, orchid friends and the Internet, to make a discussion with you about Chunlan.

First, the relationship between seedling emergence rate and variety. The seedling rate of bluegrass has a certain relationship with varieties. Some varieties are easy to seedling and easy to raise, while others are both difficult to raise and not good. Generally speaking, some butterflies, multi-petaled butterflies and other butterflies have a high seedling rate, and butterflies are also easy to blossom; lotus seedlings are general, and when the mother grass is strong, there are occasional double ridges, but it is rare to see the second and third generations, especially the green clouds (returning to lotus) are the most difficult to sprout, but when the grass grows big, the flowering is OK. There are all kinds of plum immortals, and some have a high seedling rate, which is often full of flowers, and the lowest rate is also in plums. This kind of flowers are extremely difficult to raise. When the new grass is issued, the old seedlings will retreat, and it is not easy to rise flowers; there are also how many seedlings of art grasses, but some of them are difficult to raise, and those who are too skilled are even more difficult to serve.

Second, the strong and thin of bluegrass and the size of orchid clump have a certain relationship with the seedling rate. Orchid friends often encounter this situation. For the same variety of orchid grass, the seedling rate in the rear ridge is higher than that in the front ridge, and the seedling rate of weak grass is higher than that of strong grass. In fact, this is related to the survival instinct of plants, when the grass is weak (except Reed head). Plants in order to survive and reproduce, often show the phenomenon of multiple seedlings, mainly asexual reproduction, but the orchid seedlings are often weak and will not produce the second generation buds within a year. In the second year, the grass is not big, and some are even getting smaller and smaller, so it is very difficult for it to start, and the back ridge of multi-seedling conjoined body is slightly better. Some seedlings are strong and conjoined orchids are large, mainly through sexual reproduction to complete reproduction, that is, to blossom and bear fruit, so those with strong seedlings and conjoined bodies are easy to blossom and have less grass, but the grass is strong and the plant type is large, and the new seedlings are getting stronger every year, and the number of leaves is more than that of the old grass. In order to pursue the goal of multiple seedlings and large seedlings, it is necessary to divide plants at the right time to make them grow more. In order to grow strong seedlings, orchids can not be divided into too small. Orchids are plants that like to gather, and large grasses should have at least three seedlings. Generally speaking, it is appropriate to divide the number of seedlings into three to five seedlings. This kind of grass is easy to cultivate and easy to bloom. However, for some grass with higher prices, it is also possible to buy varieties and pursue the number of seedlings.

Third, the cultivation and care in the later stage is closely related to the germination rate of bluegrass and the sturdy and thin grass. First of all, according to the strength and size of orchid seedlings, choose pots, prepare reasonable plant materials, pots should be small rather than large, weak grass, grass on the basin alone, plant material fat slightly lighter, plant material particles should also be small. The planting depth of bluegrass is also related to the seedling rate and the sturdiness of bluegrass, such as deep planting, easy to grow seedlings, tall and standing seedlings, but thin grass, not strong Reed head; shallow planting, few seedlings, but strong Reed head, easy to bloom. Therefore, according to the known characteristics of bluegrass, the depth of orchid planting should be adjusted appropriately, and the bluegrass should be planted to the height where the Reed head looks like dew. Watering, when the orchid bud sprouts in early spring, the wet germination rate is higher than dry, so it should be kept moist, and some fertilizers should be used to promote the budding. The hard granular planting species should be wet rather than dry, and should also be moistened to the opening of the leaf tip of the new seedling, which is conducive to the growth of orchid seedlings. Apply some growing fertilizer, when the new grass is half big, in summer, watering should be slightly controlled, watering interval should be lengthened, but watering should be thoroughly watered. Appropriate use of some fertilizers to help growth and strong grass, to the autumn and winter season, the amount of water should be less, so that the growth of new seedlings, but also conducive to the development of buds.

4. the environmental light condition is also closely related to the seedling emergence rate, the size of orchid seedlings and the flowering rate. The environment light is strong, the orchid plant is strong, the plant type is short, the leaf color is light, it is easy to flower, but the seedling rate is not high; the light is weak, the seedling emergence rate of orchid seedlings is slightly higher, but the plant type is tall, the Reed head is not strong, it is not easy to flower, the disease resistance is poor, and the adaptation is slow after changing the environment. In order to make bluegrass both seedling rate and strong, it is very important to give reasonable light, early spring, late autumn and winter, should be given sufficient scattered light, bluegrass growing period in summer, there should also be reasonable scattered light, but can not put bluegrass in the hot sun. The application of phosphorus and potassium fertilizer in autumn can make the orchid strong, the new grass Reed head increased, and accumulate enough nutrition for the multiple seedlings and strong seedlings in the second year.
